What defines a first-degree trespass?

First-degree trespass in Missouri is specifically defined as knowingly entering unlawfully or remaining unlawfully in a building. This definition emphasizes the element of knowledge and unlawful intent, indicating that the person was aware they were committing an unlawful act when entering or staying in the premises.

This aspect of the law distinguishes first-degree trespass from other types of trespass, which may not involve a building or a clear intent to enter unlawfully. Additionally, first-degree trespass typically includes structures that people have a reasonable expectation of privacy in, thus elevating the severity of the offense compared to simply walking onto someone else's lawn or occupying an unsecured area without permission.

The focus on buildings is critical because it reflects the greater societal interest in protecting private property rights, especially in circumstances where intrusions may compromise safety and privacy. Thus, the key components of knowingly entering or remaining in a building unlawfully are what characterize first-degree trespass.
